IMPROVEMENT lN GANG-FLOWS.

Specification forming part of Letters Patent No. 95,539, dated October5, 1869.

To all whom. it may concern.-

Be it known that we, J. N. THOMPSON and WILLIAM KENADY, of the town ofBelpassi, in the county of Marion,in the State of Oregon, have inventeda new and Improved Gang- Plow; and we do hereby declare the following tobe a full and exact description of the same, reference being had to theaccompanying drawings and the letters and figures of reference markedthereon.

The particular purpose of the invention is to cheapen the constructionof gang-plows by dispensing witha considerable'portion of ironworkcommonly used, and providing a tool that any farmer, with the help of acountry smith,can construct in short time at his leisure while he may beidle at home, making it as simple and effective as those of more costlyconstruction.

The mechanism is chiefly of wood, and consists of the parts describedbelow, to wit:

Figure 1 is a plan. Fig. 2 is an elevation.-

A is a lever by which the plows are thrown out of ground and elevated onthe wheels preparatory to leaving work. B is another lever, constructedas follows: Its larger end resting on the axle K in such a way that itcan advance forward or backward, as circumstances require, about itsmiddle point a swiveljoint, D, is made, which is firmly fastened to theplow-frame O. The upper part of this swivel is provided with a nut andscrew, E, which, by screwing or unscrewing, raises or lowers the depthof furrow. In this it is partly assisted by the clevis M and theadjusting-holes above and below. I The ends of the clevis M are securedto theaxle by a link, L. The rear end of this lever B is connected withthe lever A by a link, F. The lever A takes hold of the lever A andpresses it down under his feet toward the fastening-hook I. The firstresult of this motion is to throw the clevis M against the point N inthe lever 'B.

This throws the plows out of ground, and by continuing this downwardpressure on the lever A (the plows being now out of ground) the plowsare raised clear of the ground and are ready to leave the field, as soonas the end of the lever A is fastened down by the hook I.

An ordinary pair of fore wheels of a wagon will answer the purpose for atruck, and the farmer can take two common plows, unstock them and placethem on this frame 0, and be at no expense other than making the twolevers, with their joints and links and the hook I, with the beam H.

WVe claim The levers A and B, the swivel-joint D, nut and screw E, linkF, fulcrum G, beam H, and hook I, together with the adjusting-keys J,

or their equivalents, substantially as described,

and for the purpose set forth.
